Allozyme Variation In Hellianthus Praecox Ssp. Hirtus, A Rare Sunflower From Southern Texas, Loren H. Reiseberg, Michael F. Doyle
Allozyme Variation In Hellianthus Praecox Ssp. Hirtus, A Rare Sunflower From Southern Texas, Loren H. Reiseberg, Michael F. Doyle
Aliso: A Journal of Systematic and Floristic Botany
Allozyme data were used to evaluate the genetic status of a rare endemic sunflower from Texas, Helianthus praecox ssp. hirtus. Comprising approximately 200 plants, the taxon is presently known from a single population in the Carrizo Springs region of Southern Texas. Electrophoretic examination of 17 enzyme loci revealed that ssp. hirtus is genetically similar to, but distinct from, the two more widespread subspecies of H. praecox: ssp. praecox and ssp. runyonii. Levels of genetic variation in the single population of ssp. hirtus (P = 0.4 7, A = 1.88, and H = 0.17) are similar to those …

University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes the parts of a pesticide label to aid understanding and promote safe and effective use of pesticide products.
Pesticide information can be provided to end users through labels and labeling. Not all pesticide products have labeling. While the words are similar, they have distinctly different meanings.
Nesting Of Raptors Uncommon In Iowa: Summary And New Records, Dean M. Roosa, Jon Stravers
Nesting Of Raptors Uncommon In Iowa: Summary And New Records, Dean M. Roosa, Jon Stravers
Journal of the Iowa Academy of Science: JIAS
The nesting status of the Turkey Vulture, Bald Eagle, Northern Harrier, Sharp-shinned Hawk, Cooper's Hawk, Red-shouldered Hawk, Broad-winged Hawk, Swainson's Hawk, Peregrine Falcon, Common Barn-Owl, Burrowing Owl, Long-eared Owl and Short-eared Owl is reviewed and previously unpublished records added. Also the potential for the Northern Saw-whet Owl and Osprey to nest in Iowa is discussed. Although several species are on the brink of extirpation as part of Iowa's nesting avifauna, the Bald Eagle has returned as a regular nester. Over 100 previously unpublished nesting reports and some management recommendations are included.
